Combined heat and power (CHP), or cogeneration, is the use of a heat engine or power station to simultaneously generate both electricity and heat. CHP captures the waste heat produced by electricity generation and allows that thermal energy to be used. CHP is not a single technology, but an integrated energy system that can be modified depending upon the energy needs of the end user.
Installing a CHP system enables a facility to increase operational efficiency and decrease energy costs. CHP requires less fuel (therefore producing fewer harmful emissions) and avoids losses that occur when electricity travels over power lines. Additionally, CHP can be designed to provide high-quality electricity and thermal energy to a site regardless of the power grid, decreasing the impact of outages and improving power quality for sensitive equipment.
